Abstract (en)
[origin: EP3051005A1] The purpose of the present invention is to provide a method for treating the surface of an aluminum can, in which an acidic treatment solution that is easy to handle can be used and the energy cost is sufficiently reduced. A method for treating the surface of an aluminum can, which comprises an alkali treatment step of treating the aluminum can with an alkaline treatment solution and an acid treatment step of treating the aluminum can that has been subjected to the alkali treatment step with an acidic treatment solution, wherein the etching amount to be employed in the alkali treatment step is less than 50 mg/m2. It is preferred that the alkaline treatment solution contains at least one ion selected from the group consisting of a sodium ion, a potassium ion and an ammonium ion.
